Kumarasamy Thangaraj takes a blood sample from an Andaman islander, as part of his research into the genetics of India's castes. DR. KUMARASAMY THANGARAJ
Kumarasamy Thangaraj traveled 840 miles (1,350 km) off of the eastern coast of India by plane, then ship, then six hours by car, then ship again to collect blood samples from an isolated tribe of hunter-gatherers on the Andaman Islands. Their blood, he explained through an interpreter, would help him understand a pivotal moment in India’s genetic history.
